Water Spotting

 

 

Description

Blisters appear as swellings on the surface of the paint and vary considerably in both size and density. Coarse blisters, larger than 1.5 mm in diameter, generally occur in patches.

Cause

Water droplets impacting on, and evaporating from, the surface.

The marks may result from:

  1. Exposure of the paint film to rain or water splashes before it has fully hardened.
  2. Rain or water splashes on an excessively thick film of wax polish.

 

Prevention

  1. Protect paint surfaces from water until fully hardened.
  2. Do not allow excessive wax build up on the surface.

 

Rectification

Dewax the affected area, flat lightly, compound and polish, repeating if necessary. In severe cases repaint the topcoat.
